Even within a single vicinity, different Drosera species can be remarkably different from each other – in size, colour, and general appearance.
However, this description fits all “sundews”:
Sundews are “flypaper” plants that trap prey in sticky hairs on their leaves. They make up one of the largest groups of carnivorous plants. Long tentacles protrude from their leaves, each with a sticky gland at the tip. These droplets look like dew glistening in the sun, thus their name. The glands produce nectar to attract prey, powerful adhesive to trap it, and enzymes to digest it. Once an insect becomes stuck, nearby tentacles coil around the insect and smother it.
